The bait is good. However let me clarify some things for you;
The featured activities have always [b]featured[/b] [i]endgame[/i] [u]activities[/u], you know, the stuff that's current.
If a daily mission or Nightfall was for The Dark Below, and someone didn't have that DLC, tough luck, no loot for them.
In this case, tough luck for you. By the way you type it seems like you don't have a job. When you do, you'll be able to buy 2 or 3 TTKs in a day's work.
